The majority of homes are now equipped with a flat screen TV is compatible with High Definition. So the war rages among manufacturers and it is sometimes difficult to navigate in this world who could scare the less tech savvy among us. Especially if you need these displays for retail displays, you need to understand the differences between them.

A comparable equipment, the question most often returning is what technology to choose between a Plasma , an LCD TV and now a LED TV . Especially now that every manufacturer brings innovations based on screen type.

Plasma screens

What’s this? The technique of image reproduction from a mixture of gases (Argon and Xenon) contained between two glass plates. The emission of an electric current through the mixture to create the plasma .

Interests / benefits

The reasons to opt for a plasma screen are multiple:

You get better contrast with a quality of obvious black and a wide range of colors. It is the ideal solution to watch your movies on Blu-Ray or DVD
The plasma screens are larger than those from other families (at least 94 cm)
The Plasma screens are now more accessible in terms of prices.

Disadvantages

Beyond these real qualities, screens Plasma suffer from some flaws.

Their weight. In fact, slab glass is heavier compared to plastic tiles of LCD or LED. Reward so be careful if you need to hang the Plasma screen to your wall and choose the proper outlet.
Power consumption is higher (around 20% compared to a LCD TV and LED )
This type of screen requires a relatively large part due to the screen size
The plasma screens are not optimized for video games. A persistent image syndrome (Burning) may occur, even if the last Plasma have made ​​great progress on the subject. It is for example not possible to continue to collect the logo of a chain once the TV off after extended use.
Why choose a Plasma screen?
You’re a cinephile DVD-vore? Plasma is for you. The screens are great, the color rendition is more natural, the more fluid picture and very high contrast. Their perfect for watching a movie in a dark room use!

Innovations

Some manufacturers such as LG offers models with a “Photo mode”. This allows the TV to reproduce images (or other multimedia content) on the screen with a particularly faithful to the original clarity and resolution. Also note that these images can be displayed with effects such as monochrome, sepia, oil painting and sticker …

There are now several models of plasma screens equipped with the THX display certification. It is the standard for electronic audiovisual entertainment products.

Also be aware that plasma TVs now include HDMI and USB ports.

Finally, note that the problem of burning effect was attenuated on the new generation plasmas. Affichées too long, still images could continue to see (superimposed) for hours. Now, the latest models use technology capable of preventing this phenomenon.

It is the choice of the market: the LCD is the technology adopted mainly by buyers TV
A wider range including more choices in screen size
A much higher brightness plasma for best viewing in a bright room
The LCD screens are consume less energy than plasma screens
The image is also finer and more accurate with native resolutions often higher than the Plasma .

Disadvantages

The LCD screens are unfortunately more fragile. Attention to the syndrome of dead pixel! Whether your screen is on or off, a black pixel can remain after a bad shot. He may be tiny, but it remains still, you will not see him, especially if he is in the middle of the screen!
The contrasts are lower than for a plasma screen . But manufacturers have made ​​great strides in this area, catching up slowly behind them.
Plasma Compared to the response time of the image is higher, giving the impression of a less fluid picture. But again, manufacturers have made great strides.
Why choose an LCD screen?

The LCD screens are the most versatile. They cover the vast majority of uses: video games, TV, Cinema, Multimedia …

It is also the ideal technological solution for extra screen. If you are looking for a second TV, or if you have a smaller room: go for a LCD screen!

Innovations

We currently know of screens LCD touch and / or able to connect to the Internet.

How do you analyze a used car to make certain it is up to par? It can seem difficult but with a few tips it’s not as hard as you think. Recently we had to used these tips to purchase a used car St George Utah for my son as his used car had broken down on him. Here are a few pointers for you to try.

1. How do I know if the car of my choice has ever had an accident?

This task is relatively difficult for the lay person – especially if the repair were real professionals at work. But most of them are rather expensive cars affected. For cheap cars to pay an expensive repair to cover up the accident is barely useful. However, you should be suspicious, even if only one of the following things you see or experience: – The paint is different light or dark in some places – There are paint traces in places where no other paint (eg the strut, to rubber seals, etc.) – it’s different on the inside of the doors, hood or trunk lid. – There are extremely different gap dimensions at eg doors or bumpers – The straight line of the car is not good (can also only have been a sharp move to the curb – but better safe than sorry).

It becomes dangerous when, for example, a trader wants to write “without warranty” in the purchase contract. If the dealer wants to pull out of his responsibility, all the alarm bells should be ringing. Also a phrase that is taken is always like, “As seen and test driven.” As can later be said quickly, “That was already on the test drive so”.

3. How do I know if the mileage has been tampered with? The manipulation of the mileage is harder and less of a problem these days. When cars still had half the dash to be expanded with an analog odometer it’s possible, but in the new cars with computer odometers it is fairly difficult. But if someone changes the mileage from 287,000 to 160,000, it is quite difficult to find out. The best indication here is the wear of the interior. In a car with 70,000 miles pedals, shift knob and seats are still in pretty good condition. Are the seats already sat through and recognize no more grooves on the pedals, it is better to choose a different car or another dealer.

4. How important is a service book?

Most important when buying a used car is the service record. Here you can see at a glance how well the car was maintained? Especially in relatively new cars, there should definitely be a service issue. Even better, it is, of course, if even the original bills with it. Despite existing service book you should be suspicious if the stamp for the inspections of the same traders who sold the car and the stamp from year to year is weaker, the signature is always the same and the pen color and intensity is the same.

5. The car has been my choice over 100,000 mi – that’s too much?

The mileage alone does not say much about the car and out of the state. It is more important to see the conditions here. Was the previous owner, a representative who is driven mainly long stretches of motorway and the car has always been on time for service, it is often better than a car with 40,000 miles that have been put back only in stop and go traffic. every 100,000 miles, you should but also pay attention to whether wearing parts have been replaced. Is not the case, will be added over the next several thousand kilometers lot to repair. You should also check with exactly how many kilometers costly replacement of consumables such as a belt is necessary.

After you get in to test drive the car, after checking the oil level, coolant and brake fluid in the engine compartment, it is now a driving characteristics. A good method for the first impression is to let the seller drive. This has the advantage so that you can watch as a passenger more because you are not distracted by driving an unfamiliar vehicle. The test drive should take place in daylight, as a night drive requires more concentration. That’s how we went about our test drive when we were looking at a St George used car when we were recently on vacation.

Look at starting a cold engine on the indicator lights: If the machine starts quickly (do not forget the pre-heating in older diesels), all indicator lights should be extinguished within a few seconds. This is usually a sign for OK all important systems that serve the driving and safety. When the engine is running smoothly, you can get off again and convince yourself of the function of the headlight and turn signals, headlight flasher, fog lights and brake lights and light circuit. Now let the seller go a few miles and watch his driving style. It can be concluded from the test drive, first, whether he (as a private seller) is familiar with the vehicle, on the other hand, if his driving style maybe to conceal deficiencies.

Be careful as the car accelerates and whether the gear shift runs smoothly and the automatic shifts smoothly. As relaxed seated passenger is taken usually the suspension and tire noise more true. Worn-out shock absorbers and damaged axle feel and hear even a layman. You can compare features such as fan, air conditioning, power windows, sunroof, navigation, radio etc., without having to concentrate on the traffic. Turn on the radio but turn it off again, since it’s a distraction factor.
Ask them finally to be allowed to take over in a parking lot or an open road without much traffic the control. You must first have inquired as to how the vehicle is currently insured for all damages resulting from a test drive will be charged to the driver. The liability is however limited by liability and comprehensive insurance on the deductible and the downgrading of damage to the vehicle owner. Also, traffic adversities of course, go to the driver who caused them account. Do not drive with an unknown or insufficiently insured car because you assume all risk and liability for any damages!

When all functions test drive test itself

Once you sit behind the wheel and seat and mirror set, try all the features that you could not test so far. Then press for the horn and wipers to test and get familiar with the gear shift: As you put the car in reverse, are all the gears to shift well and evenly in the state? Then, the clutch is checked for proper operation. To do this, pull the parking brake, place the 3 Gear and let out the clutch lever slowly. The engine must now die, otherwise the clutch will slip through and must be repaired soon. Likewise, can you feel the behavior of the engine during this procedure, as it is with the stock: Shaking, shaking the engine noticeably before it stalls, the motor bearings are probably worn.

Now it is on the slopes: Go for a test drive on a straight street with little traffic as possible and take your hands off the steering wheel. Then continuously pulls the car to the left or right, is probably wrong track. Even an accident injury can be the cause of a warped track.

The function of the brake test also on a straight and dry road with little traffic. When the brake pedal a uniform and largely noise-free delay must occur. The braking effect is different on both sides, when the vehicle moves to the right or left. In this case, adjustments are needed in the workshop. During the braking test, you should also test the effect of the ABS. It is best to do on a road with loose gravel or slippery surfaces on the brakes at speed 40, if nobody is at risk. If you get out now and see clear grinding marks, at least one tire has blocked and denied the ABS. A repair is expensive, a defective ABS prevents the allocation of inspection sticker.

Check gearbox, starter motor and acceleration

Now test in detail the transition circuit by trying all combinations during the test drive, depending on traffic. Fast boot and downshifting and gear skipping shows whether the transmission is running smoothly or are suspicious noises. Ensure vehicles with turbochargers on the passage and the acoustics desselbigen: A soft singing or whistling when accelerating discreet is safe, louder noises may indicate problems and costly repairs. Move the car in city mode with a lot of stop and go and the roads and highway mode with high gears at low, medium and high speeds. Also try whether the steering wheel starts to vibrate at higher speeds.

For a full throttle, the coolant thermometer must (if present) do not rise too much, but must quickly when driving slowly recover. Otherwise, a problem with the thermostat could be. If an oil pressure gauge is available, you can check the engine for a fast ride. Hold during the test drive in a safe place, turn the idle and watch the oil pressure. He sinks drastically, the engine has problems with the lubricant circulation and probably not very long life expectancy more.

Finally, you check the steering at low speeds and when parking. They are at full impacts noises? Does it clear the game? When parallel parking, you can check if the steering is good. Do you need to boost too much or it creaks audibly, this indicates problems in the steering gear.

Take time for the test drive

A detailed test drive, as described here, usually takes only 30 to 40 minutes to complete, but well worth it in any case. A seller who has something to hide love it when buyers concede without hesitation. Remember, however, that one can not expect the equivalent of a new car at a used car price. Wear parts go as well as other components often unexpectedly broken and are due from certain odometer readings. Defects with the new owner has therefore always to be expected.

On the other hand, can also give a room for negotiation defects that become apparent during the test drive, the buyers. However, the private seller can not talk to him, he is probably untrustworthy and hopes for a less qualified buyers. In this case worth to abandon the vehicle, the liability for defects is excluded in a private sale, in most cases already in the contract.
